The Race of my Face(book)

I attended a lecture last night on promotion and publicity tactics for authors and heard a curious fact. Apparently Facebook is considered to be an "overwhelmingly White" social networking site, whereas Myspace caters to a more "ethnic audience." I've just begun to dip my toe into social networking (reluctantly, I might add) and can't believe we've already been divided.

Anybody out there want to confirm the PR expert's analysis?

Peace...
